摘要
为提高道路交通设备运维管理的智能化水平,实现交通信控远程优化与评价,推动交通状态社会化应用,设计了基于4G通信的交通信控无线运维系统。首先,构建了系统的基本架构,指出该系统由连接不同设备源的接口层、管理多种数据的中心层、支持多重应用的平台层构成。其次,设计了独立的无线通信设备,使其具有多种通信及检测功能,可实现对不同信号机的无缝兼容连接。再次,实现了运维功能模块,包括故障运维、流量及交通优化、实时状态显示等应用子模块。最后,通过独立于交警专网的实例验证了系统的各个功能,结果表明运维系统实现了信号机故障的无线管理,使优化技术得以远程分析和验证,可进一步推动智能交通的社会化应用。
In order to improve the intelligent level of maintenance management of road traffic equipment,realize the remote optimization and evaluation of traffic signal control, and promote the social applicationof traffic state, a traffic signal controller wireless operation and maintenance system based on 4 G communication was designed. Firstly, the basic architecture of the system was built, including an interface layerconnecting different equipment, a central layer managing multiple data, and a platform layer supportingvarious applications. Secondly, an independent wireless communication device was designed to providemultiple communication and detection functions, which can achieve compatible connection to differentcontrollers. Thirdly, the maintenance function modules were implemented, including fault maintenance,traffic and optimization, real-time state display and other application modules. Finally, the system functions were tested by an example independent of the traffic police special network. The results show thatthe operation and maintenance system achieves the wireless management of controllers′ failures, enablesthe optimization technology to be remotely analyzed and verified, and can promote the applications of intelligent traffic.
